摘　　要：储层在钻井、完井、采油、增产和修井的各个作业环节都有可能受到不同程度的污染和伤害 ,尤其是与地层配伍性差的各种入井液 ,将会造成地层污染 ,从而使油井产量下降 ,采收率降低 ,因此加强入井液的研究是保护油层、防止伤害的重要环节。为了能够在油气层和井筒之间产生一条清洁的通道 ,增加油气井的产能 ,加强了射孔液、射孔工艺、射孔损害机理、射孔参数的研究 ,尽量避免或减少射孔过程中对油气层的伤害 ,保护馆陶组砂岩油气藏 。The reservoir may be polluted and injured during the course of drilling & cementing & production & repairing.The fluid such as drilling fluid & repairing well fluid & injected water will pollute the reservoir if they are not fit with the reservoir,so that the production of the oil well is low slowly.It is an important safeguarding of protect oil & gas reservoir to strengthen the research of the fluid which is injected into the formation.Perforation completion is an important mothed that may come into a permeable passageway between the reservoir and the well bottom,it may increase the production on oil well and reduce the damage to the oil & gas reservoir.Hence we must strengthen the research on perforating fluid,perforation technology,injury mechanism,perforation parameters to avoid or reduce the damage to the oil & gas reservoir in the perforation process.
